FRANK J. BALLINTINE, .OF KANSAS CITY, MISSOURI,

ASSIGNOR TO PARKER/P WASHINGTON COMPANY, OF KANSAS CITY, MISSOURI, A CORPORATION OF WEST VIRGINIA.

MACHINE FOR HEATING SURFACES.

To all whom it may concern: Be it known that I, FRANK J. BALLIN- TINE, a citizen of the United States, and resident of Kansas City, Missouri, have invented certain new and useful Improvements in Machines for Heating Surfaces, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in machines for heating surfaces, the object of my invention being generally to improve the construction of the combustion chamber, blower and the means for elevating the hood in machines of this class, thereby reducing to a minimum the weight of the heating apparatus and increasing the efiiciency of the lpprners with a minimum amount of liquid rel.

For the above purposes my invention consists in certain novel features of construction and arrangement of parts as will be hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, in which:

Figure 1 is an elevation of the complete machine; Fig. 2 is a rear elevation of the hood, combustion chamber and means for elevating the hood showing the relative posit-ion of the blower and combustion chamber, a portion of the machine frame being shown in sect-ion; Fig. 3 is a vertical sectional elevation through the hood and combustion chamber with a portion of the blower casing being broken away to illustrate the position of the burner therein; and, Fig. 4 is a sectional plan taken on the line 4.4 of Fig. 3.

Referring by numerals to the accompanying drawings: 1 designates the machine frame. For convenience in operating the machine the frame is mounted upon the ranged to be driven by an engine such as 4. 5 designates a steam generator supported ply steam to the engine 4.

6 designates a blower casing supported by the standards 7 which are secured to the machine frame adjacent the rear end of the frame. Mounted in the walls of the casing 6 is a shaft 8 having on its one end a pulley 9. An engine such as 10 is supported by Specification of Letters Patent.

ing 6 and is connected with the pulley 9 by the belt 11. This engine is designed to be supplied with steam from the steam generator 5 by any suit-able connections (not shown). Blades (not shown) are supported upon the shaft 8 and arranged to rotate within the casing 6. A truncated coneshaped combustion chamber 12 is connected with the casing 6 and supported from the machine frame by the hangers 13. A perforated baffle-plate 14 is secured within the combustion chamber adjacent its lower end and the entire combustion chamber is lined with asbestos 15, fire brick or the like. A burner tube 16 is inserted through the blower casing and projects downwardly therethrough and terminates within the combustion chamber. A valve 17 is connected with the burner tube 16 and is arranged to be supplied with steam and hydro carbon under pressurethrough the pipes 18 and 19. Located in the pipe 18, adjacent the valve 17, is a valve 20 to control the steam entering the burner tube. A similar valve 21 is located in the pipe 19 to control the passage of oil under pressure to the burner. By this arrangement of burners I am enabled, by manipulating the valves 20 and 21, to regulate to a nicety the amount of steam or oil to the burner, and, by manipulation of the valve 17 I am enabled to control the combined oil and steam entering the burner tube.

A hood 22, has a reduced neck portion 23, which neck portion, embraces the lower end of the combustion chamber 12. Stubs 24 are fastened to the neck portion 23 of-rhe hood 22 and the free ends of an inverted U-shaped hanger 25 are secured to said stubs. Braces 26 are secured to the hood at one end and at their other end to the stubs, and said U-shaped hanger embraces and is v secured to the stubs by means of the nuts wheels 2 and 3, the former of which are ar- 5 27 A piston rod 28 is fixed to the upper end of the hanger 25 and projects into a cylinder 29 wherein a fluid, under pressure, in the machine frame and designed to supacts on a piston (not shown) connected to the rod 28 and elevates the hood 22.

While I have shown my apparatus mounted upon a wheeled truck and have illustrated an engine for moving the truck and have shown a blower designed to be driven by an engine mounted on the machine frame 5 and have illustrated and described a U- the machine frame adjacent the blower casshaped hanger for the hood, Which hanger is operated by a piston and a cylinder in which air or steam is injected and have further illustrated a conical combustion chamber, I do not desire to be understood as limiting myself to the use of this specific construction of these parts.

In the practical operation of the device the machine is positioned at a point upon an asphalt paving where it is desired to make a repair and the hood lowered into engagement with the pavement. The oil and steam valves of the burner are then opened and adjusted to a proper mixture of oil and steam to create a perfect combustion of oil and steam and the oil issuing from the burner tube 16 is then ignited. It is obvious that by reason of the employment of a single burner too great a heat might be discharged upon a limited area of paving, and, to provide a means for breaking up and distributing this flame I have provided a baffle plate which is fixed adjacent the lower end of the combustion chamber through which plate the flame is discharged in a number of small jets. After the burner is ignited and the valves regulated to the proper adjustment for a perfect combustion, the engine 10 is set in motion and the blades of the fan within the casing 6 are rotated, thus causing a blast of air to discharge directly into the combustion chamber. By this arrangement of burner tube, blower, combustion chamber and baflie plate I am enabled to attain the maximum amount of heat in a minimum of time consuming a minimum amount of fuel.

Heretofore the surface-heating devices of this class have employed cumbersome and extremely heavy constructions of combustion chambers which necessitated the construction of extremely large and heavy truck frames. By the construction shown, I have reduced not only the weight of the combustion chamber but have reduced to a minimum the number of parts employed in such a machine.

I claim:

1. In a machine for heating surfaces, a frame, a vertically disposed combustion chamber carried by said frame, a hood provided with a neck mounted over the lower end of said combustion chamber, a fan blower casing connected with the opposite end of the combustion chamber, a vertically disposed burner projecting into the upper end of said combustion chamber, a fan mounted in said fan blower casing above the discharge end of the burner, and a horizontally disposed baffle plate located in the combustion chamber between the hood and fan blower and beneath the discharge end of the burner.
